7. the braking system is the mechanism used to control the rotation stop of the rotor shaft and axial rotation of the turbine. When the wind speed exceeds the ability of the turbine and during repair, maintenance. 8. wind direction is rotated neck axis is a rotation control room, so that the rotor is wind direction by the system tape Thailand connected to have a relationship with tiller was wind direction at the top of the machine. 9. measuring wind speed and wind direction, connect the signal cable to log on to the computer as a pointer to the size of the speed and direction of the wind, so that the computer will control the other mechanisms properly. 10. a wind turbine towers bear a portion of the above.
